When does this happen?

IF When using vLLM with temperature=0 and top_p=1.0, batch inference may produce empty responses with no generated tokens.

How others solved it

THEN To avoid empty outputs, set a small non-zero temperature like 1e-3 or 1e-2 instead of exactly 0. Alternatively, implement a min_tokens parameter in the vLLM sampling configuration or add post-processing to detect and retry empty generations.

sampling_params = SamplingParams(temperature=0.001, top_p=1.0, max_tokens=128)
